Bloomberg is a New York company, both in its headquarters and in its corporate culture.

Expanding its research and development and VC arm to San Francisco meant it had to relax a bit in order to court west coast developers who have come to expect certain things at startups: Couches, snacks and an open floor plan.

Bloomberg ditched the normal startup flair of ping pong tables and bean bags and opted for an entryway that's a little bit cooler: an open-air tank complete with two sting rays who live below a data visualization.

The office is in Pac-Bell's old headquarters, built in 1925, at 140 New Montgomery St. in SOMA. The 22nd floor where Bloomberg is located was used as the women's cafeteria.
